Abstract

The invention discloses an anti-aging automobile distributor cover. The distributor cover is composed of following components in parts by weight: 98 to 102 parts of PET resin, 11 to 18 parts of straw ash, 3 to 4 parts of potash feldspar powder, 1 to 2 parts of diphenyl cresol phosphate, 1 to 2 parts of anti-oxidant 168, 2 to 3 parts of attapulgite, 1 to 2 parts of Y-chloropropyltrimethoxysilane, 2 to 3 parts of leukonin, 2 to 3 parts of alkylolamides, 1 to 2 parts of 2-mercapto benzimidazole, 0.8 to 1 part of 1,4-butanedioldimethacrylate, 0.2 to 0.4 part of dicumyl peroxide, and 2 to 4 parts of modification auxiliary agent. The anti-aging automobile distributor cover has the advantages of high-temperature resistance, cracking resistance, aging resistance, and excellent flame-retardant performance. The straw ash contains a large amount of metal oxides, and thus the weight of the distributor cover is reduced.

Description

A kind of anti-aging automobile distributor controlled lid

Technical field

The present invention relates generally to a kind of distributor plate, relates in particular to a kind of anti-aging automobile distributor controlled lid.

Background technology

PET is the polymkeric substance of oyster white or light yellow highly crystalline, surface smoothing and glossy.Anti-creep, fatigue resistance, rub resistance are good, wear away little and hardness is high, have toughness maximum in thermoplastics; Electrical insulation capability is good, and temperature influence is little, but corona resistance is relatively poor.Nontoxic, weathering resistance, chemical proof good stability, water-intake rate is low, and weak acid resistant and organic solvent, but thermo-labile water soaking are not alkaline-resisting.The second-order transition temperature of PET resin is higher, and crystallization velocity is slow, and molding cycle is long, and shaping cycle is long, and molding shrinkage is large, poor dimensional stability, and the moulding of crystallization is fragility, and thermotolerance is low etc.; The large multiplex straw ash cinder of the automobile distributor controlled lid of traditional mode of production strengthens the bad performances such as heat-drawn wire of improving PET, but automobile distributor controlled lid still crack, damage etc. can often occur, affected the normal use of car, therefore easily cause potential safety hazard, a kind of new, high performance distributor plate is necessary for the development of automobile cause.
